A superficial partial-thickness burn involves damage to the epidermis and part of the dermis. This type of burn is characterized by the presence of redness, blisters, and sensitivity to temperature and touch, suggesting that the nerve endings are still intact. The blisters that form can be thick, and such burns are indeed painful due to the exposed nerve endings in the affected area.

The healing time for superficial partial-thickness burns typically ranges from 1 to 3 weeks, depending on the severity of the burn and other factors such as individual health and proper care. The ability of the skin to heal, regenerate, and form the epidermal layer generally results in minimal to moderate scarring, which is why option B accurately describes both the characteristics and the expected outcome of a superficial partial-thickness burn.

In contrast, the other options suggest outcomes that align more closely with deeper burns or different burn classifications. For instance, scarring with skin grafts is more common with deep partial-thickness burns or full-thickness burns where significant tissue loss occurs. Non-painful burns that heal over three weeks typically relate to full-thickness burns where nerve endings have been destroyed, and complete loss of sensation pertains to deeper injuries that affect the dermis or sub
